Isset function not working.

[zfred09]

My goal of this is to say if $var isnt set then set it, but when I goto the page nothing shows up, but then if I refresh the page the string will show up.  It's as if when I first load the page it just doesn't read the isset part or something.

[code]if(!isset($var)){$_SESSION['var']="23213123";} echo "$var";[/code]

I don't have an answer to your question, but you should [i]really[/i] be scripting with register_globals switched off in your php.ini

if(!isset($var)){$_SESSION['var']="23213123";} echo "$var";

When you first load the page var ISN'T set. $_SESSION['var'] is, but $var is not.
Change to:
if(!isset($var)){
  $var = '23213123';
  $_SESSION['var']=$var;
}
echo $var;

And it will echo every time.
ps: don't put quotes around varables that don't need them.

The fact that this isn't working makes it look like globals IS off.

I have no answer either I just wanted to comment on Semi's quote, funny shit.

Why does it work on refresh then? (Sorry if I'm missing something obvious here, been a long day!)

[Jessica]

Ah good point. If this is the entire page, you're right, RG is on.
If there's more code, perhaps $var = $_SESSION['var']; earlier on?

I dunno, either way. You're right it should be off. I think the code I posted will fix the immediate problem.

[zfred09]

That is at the very top of the page and isn't defined later on.  And what is the benefit of register globals being off? Security?

[trq]

Yes, security. Itys also allot easier to keep track of variables when there aren't mysterious globals floating around.
